Disclosed is a personal care composition comprising carboxymethyl cysteine compound and unsubstituted fatty acid, wherein the molar ratio of the carboxymethyl cysteine compound to the unsubstituted fatty acid is at least 2.5:1.

The application discloses a preparation method and application of S-adenosyl-methyl cysteine, and the preparation method comprises the following reaction: S-adenosyl-L-cysteine is methylated by using a first methyltransferase or a first methyltransferase mutant and a methyl donor to obtain S-adenosyl-methyl cysteine; or S-adenosyl-L-homocysteine is methylated by using a methyltransferase or a first methyltransferase mutant and a methyl donor to obtain S-adenosyl-methionine. The method has the characteristics of low cost and simple operation, and enables S-adenosyl-methyl cysteine to replace expensive S-adenosyl methionine (SAM) as a coenzyme and a methyl donor in a methylation reaction, and is applied to methylation modification of natural products based on a coenzyme regeneration system.
